• Seed Mix No. 5 (Table 22 -5) is a list of annual grains which may be used for cover cropping in <br />reclaimed areas, or as vegetative stabilization for areas needing protection for approximately <br />one year or less. Barley, oats, regreen, or winter wheat will be used depending on the season in <br />which seeding will be done. Cover cropping may be done alone (at times other than the <br />normal fall planting period). <br />Within the permanent mix are species that have different rates of establishment and longevity. <br />As an example, slender wheatgrass is one of the earliest establishing perennial grasses, but is <br />not as long -lived as later establishing perennial species. The annual grains establish faster than <br />the perennial species, including slender wheatgrass, and help to develop an effective cover <br />more rapidly. Establishing perennial species will have replaced most or all annual grains by the <br />next growing season. Time of seeding will determine which species is used. Winter wheat <br />seeded in the late spring or barley or oats seeded in the summer or early fall will fail to mature <br />a grain crop, and thus reduce volunteering. Cover crops have been used effectively for a <br />number of years at the Seneca II Mine. <br />• TABLE 22 -5 <br />Seed Mix No. 5 - Covet Crop <br />Species <br />1. Hordeum vulgare <br />2.
